How to work with special registers in a LCPU L0 structured project on GX Works2
Igor Lasmar posted a topic in Mitsubishi
Hello there, This is my first time here on this forum and also my first time working with this software and PLC. I am working off-line (since my PLC did not arrive yet) on GX Works 2, in a structured project type, with LCPU series and L02 type. the problem is that when trying to use any of the special registers (m8000, r23500, etc...) on my code after compile the error F1028 pops-up, on the other hand the same code with special register will work just fine in a simple project type without labels and I dont know how to make it work on my structured project with labels. -
Hi, data registers are getting full, because of extremely high speed pulsing is there any way , if the data value in register goes above the capacity of 32 bit register, it automatically attaches itself to next set of data registers so lets say if data was written in D10,D11 Upon reaching the limit, it goes to D10, D11, D12, D13 please share if there is an alternate way to do this

Hi I'm trying to set up Modbus RTU communication between FX3U PLC and a weigh module. I would use the ADPRW command using 0X03 to read the 16 bit Holding Register but in the weigh module the Data Address/Holding Register of the value I want to get is 400047 - 400048. How to translate the value in 16 bit? Thanks, Fabio

Dear All, I am facing a problem in FX2n, Infact i am making a totalizer from the flow. everything is fine. but client demands to add some totalizer value to start with totalizer. the problem is that when i add 50000 value the value of registers stucks. although i am using 32bit float register along with DEADD command for Totalizer. the makes some steady at some place. i dont know why. but i give the totalizer 0 it works fine. Any Solution regarding this will be help. Value in the D72 = 0.0003

Dear Engineerds, My Master (non siemens) doesn't see the Holding Registers of the Slave (S7-1200) plc. However the Q coils are fine and all Diagnostics don't show errors. The Hardware: S7-1200 – CPU 1215C CM PtP – CB1241 RS485 (6ES7 241-1CH30-1XB0) - Half Duplex RS584 Firmware: Modbus_Comm_Load (V3.1) Modbus_Slave (V4.0) I've tried with various DB, UDTs and manipulating HR_Start_offset parameter with no success. Could you advise what am I possibly missing? Modbus_Comm_Load_DB_Snapshot.xlsx Modbus_Slave_DB_Snapshot.xlsx

HI everyone , i will be very glad if anyone helps me to clear the doubt . I am using MX component version of 4 to connect with my CCLINK J61BT11N Board. Is there a way to read group of registers from the CC-LINK . for example, if i want to read from D0 to D5 or write D0 to D5. is there any function in MX component which helps to read the group of registers? I use MItshubi PLC .

Hello , I'm using Allen Bradley Micro850 - 2080-LC50-24QWB PLC. I downloaded a program to that PLC by CCW. My customer wants to build an application (like a GUI) on a PC which ables to read and write the I/O's , therefore he needs me to send him the registers of the I/O's that i have used in the program. so i woule like to know the register for every tag or I/O. where can i get that information from? for example , i would like to read : _IO_EM_DI_00 , how could i know what this tag's modbus register is? thanks in advance.

Hello all ... i am a new plc user.. i am using D500 for taking value as it is a latched register. i am taking value for a flow meter. i have two questions. 1. how totalizer is calculated from flow rate as my flow rate is in m3/h. 2. the value of register is gone upto 32000 approximately... i want that this value to go on.. i mean how 32 bit register is declared in plc .. a

We have Q06UDEHCPU PLC. We require to attain 1k of file registers in standard Ram. Please find our settings attached - PLC Parameter.png; When we try to down the register file – we attain the following error; “Failed to access standard Ram” error message (attached - Downloading Error.png); The program is very small – and thus we have plenty of space as well.

We have this logic (on a CP1E) the desired outcome is as follows: When a bad part is detected, force the operator to index the machine 6 times, using a holding register to prevent a power cycle from resetting the count. once 6 cycles are recorded output that the bad parts are removed AND reset the count to zero. What has actually happened so far: the count has gone to 6 and not reset. I have used CX Programmer to set the H0 value to zero but the compare still says it's equal (to 6) I have read everything i can get my hands on regarding holding registers and compare functions and i can't see what is wrong. I have no formal training on this so i'm sure it's something simple. can anyone point me in the right direction? Thanks guys

Hi All, I'm testing Cx-supervisor communication with ODT Micropower PMAC controller on modbusTCP. I'm able to establish the communication using ModbusTCP driver with cx-supervisor. But, data I'm getting in is Low word first, so not able to convert properly. If anybody has tried any other option/script for this issue? I did not found any setting in Cx-Supervisor as in Kepserver, shown in attachment below: How can we swap the registers read as a 32 bit word from controller? Thank you.

I'm using HMI DOP-B03E211 and its connected to DVP12SE11R PLC . In the DOPSOFT i would like to know how i could create a list of the whole indications in the system - once a specific indication is on, the list shows the name of that alert ( " system alarm failure") when its off the list doesnt show it . there are indications in a bit form ('1' or '0') and in a word form (temperature indication). how can i create a list that combines whole system indications including bit indications and word indications? thanks.
